Second, to provide a trap Awhich is simple and compact in structure andat the saine 1o time capable of handling relatively large quantities ofwater and is positive in oper'- ation; A Third, to provide an improvedtrapwhich is economical in structure and operates ef'- le tectivelyunder a great variety oi' condi-l tions such as variationsv in pressuresand the like.

Objects poitaiiling;` to details and economies ot my invention 'willdefinitely appear Yfrom the detailed description to follow. Theinvention clearly defined and pointed out in the claims.

A structure embodyiing` the features oi` my invention is illustrated inthe accompanying drawing, in which:

Fig. 1 is a view mainly in vertical section et a trap embodying4 thefeatures oit my invention.

Fig. 2 is a perspective view ot the vent 3G pipe and vent valve of myimprovedtrap. v Fig. 3 is a detail section showing the vent valve in itsclosed position, it being .shown in its normal open position in Fig. 1.

Referring to the drawing, I vprovide a lio-at chamber 1 adapted at itsupper end to receive a'discliarge pipe or conduit and provided with adischarge valve which in the Y structure illustrated comprises a casing2v 4G carrying the valve seat The valve 4i? means of the link 9. Theseparts are sub-l:

stantially the same as in my said patent.

rlhe float 5 has a vent 10 in the top thereof. Below the float chamberis a separating chamber 11 having an inlet connec; tion 12 at one sidethereof. This separating chamber is connected to the float chamberV bythe tube or pipe 13 which depends into the separating chamber opening ata point ad- `jacenty the bottom thereof and projects centrally into `thefloat chamber and into. the inverted float 5. I also provide a vent pipe14: which projects into the float, preferably being of the same heightas the delivery pipe 13.

depending into` the separating chamber. r his 4enlarged mouth portion 15has radially projecting ears 1h carrying the valve cage members 17 whichHoatingly support the.` cup valve v1S to coact with the lower end ot thevent pipe so that when the water in the sepmatingchamber reaches apredetermined level it automatically closes'this vent valve. The valveis shown in its closedposition in Fig. a Y Y The operation of the deviceis as Jfollows: Assuming .the trap to; be discl'iarging, that is, `thevalve open as shown in Fig. 1wlien all the water is drawn from theseparating chamber it is followed by steamv which fills l the bucket andcloses the valve. rlhe valve remains in its closed position until thenextY Ving chamber it seals the lower end of the de# liverypipe 13 butsteam may pass into thedoa-t chamber through the vent to replace anythat is condensed in the bucket or in the float chamber. llllienrsutlicient water has` accumulated in the,separatingchamber to closeA thevent valve the passage et steam into the bucket and into thev floatchamber isV cut oli, allowing the steam in the float cham-v ber andbucket to condense and permitting thefloatto tall, opening the dischargevalve,

-j water is driven Jtrom the separating chamberuntil the lowerend of thedischarge conduit is uncovered. rlhe pressure of the steam on the ventvalve is sufficient to hold This., vent pipe has an enlarged mouthportion lao it closed until suilicient water has been dis` charged toallow the steam to enter the float chamber through the pipe l?) and thepressure becomes equalized in the ['loat chamber and separating chamberand gravity acts to open the vent valve. rthe discharge valve is closedas soon as the flow` of water ceases.

My improved trap is very positive and uniform in its operation, that is,it operates when a predetermined quantity of water is collected, and thefloat does not vibrate as is the case in other types of traps.

I have illustrated and described my improvements in the form in which Ihave embodied the same in practice. I have not attempted to illustrateor describe the same in other embodiments which are entirely practical,as with other types of floats, as it is believed the disclosure madewill enable those slrilled in the art to embody or adapt my improvementsas may be desired.

VHaving thus described my invention what I claim as new and desire tosecure by Letters Patent is:

l. In a trap, the combination of alioat chamber provided with adischarge valve, an open inverted float provided with a vent at the topand operatively connected to said discharge valve, a separating chamberbelow said float chamber having an inlet connection, a delivery pipe forsaid separating chamber depending into Asaid separating chamber andopening adjacent the bottom thereof and projecting upwardly into saidiloat chamber within said lioat, a ventpipe connecting said separatingchamber with said float chamber and projectino` upwardly into said ioat,said vent pipe having an enlarged mouth depending into said separatingchamber, a valve cage suspended from said vent pipe, and a cup-likevalve embracing the lower end of said vent pipe and ioatingly supportedwithin said cage Whereby the valve is closed by the water accumulated insaid separating` chamber.

2; In a tra the combination of a float chamber provided with a dischargevalve, a ioat operatively connected to said discharge valve, aseparating chamber below said float chamber having 'an inlet connection,a delivery pipe for said separating chamber depending into saidseparating chamber and opening adjacent the bottom thereof, a vent pipeconnecting said separating chamber with said float chamber, Vsaid ventpipe having an enlarged mouth c depending into said separating chamber,and

a l'loatingly supported cup-like valve embracing the lower end of saidvent pipe whereby the valve is closed by the water accumulated in saidseparating chamber.

3. In a trap, the combination of a float chamber provided with adischarge valve, a i'loat operatively connected to said discharge valve,a separating chamber below.

said lloat chamber having an inlet connection, a delivery pipe for saidseparating Vhamber depending into said separating chamber and openingadjacent the bottom thereof, a vent pipe connecting said separatingchamber with said lioat chamber, and a lieatingly supported cup-likevalve embracing the lower end of said vent pipe whereby the valve isclosed by the water accumulated in said separating chamber.

fl. In a trap, the combination of a float chamber provided with adischarge valve, a float operatively connected to said discharge valve,a separating chamber below said float chamber having an inletconnection, a delivery pipe for said separating chamber depending intosaid separating chamber, a vent pipe connecting said separating chamberwith said 'loat chamber depending into said separating chamber, and aloatingly supported cup-like valve emb acing the lower end of said .ventpipe whereby the valve is closed by the water accumulated in saidseparating chamber.

5. In a trap, the combination of a iioat vchamber having a dischargevalve, a 'loat open at its lower end operatively connected to said valveand having a vent in its upper end, a separating chamber below saidfloat chamber and having an inlet connection, a discharge connection forsaid separating chamber to said float chamber, a vent connection forsaid separating and float cham bers, and a water actuated valve 'forsaid vent connection whereby the vent connection is closed by theaccumulating water in said separating chamber.

6. In atrap, the combination of a float chamber having a dischargevalve, a float operatively connected to said valve, a separating chamberhaving an inlet connection,

a discharge connection for said separating chamber to said floatchamber, a vent connection for said separating and float chambers, and awater actuated valve for said vent connection whereby the ventconnection is closed by the accumulating water in said separatingchamber.

7. In a trap, the combination of a float chamber having a dischargevalve, a float operatively associated with said discharge valve, aseparating chamber provided with an inlet connection, a deliveryconnection for said separating chamber to said float chamber, a ventconnection for said separating chamber and float chamber, and a normallyopen valve lor said vent connection actuated to closed position by theaccmnulating of water within said separating chamber.

S. In a trap, the combination of a chamber having a discharge valve,means for operating said valve, a separating chamber having an inletconnection, a discharge connection for said separating chamber to saidvalve chamber, e vent Connection for said selml'atllg und vulveChaunberf, and a wuter actuated valve for seid vent connection wherebythe vent connection is closed by the aeexumllatl of Water in seidseparating chamber.

In witness whereof I have hereunto set my hand.
